IIVIPROVEMENT IN N UT-FASTENERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, JOHN DAVIS, of New Bedford; in .the county of Bristol, in the State of Massachu setts, have invented a new and improved Mode of Preventing Nuts from lurnin'g Off the Bolts of Fishf Joint Railway-Bars; and I do hereby declare thatth' following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention consists .ina metallic bar, placed on the web of the rail, under the nuts, with clasps passing under the rail and turned against the web, &c.

Figure'l is a perspective view of a iish-joint, with my invention applied to it.

Figure 2 is a perspective view of my invention, re' moved from fig. 1.

Fig. 1. A1 is the bar.

Bl B1, .the ends turned up against the nuts to pre vent it sliding endways.

Cl C, the clasps.

Fig. 2. A2 is the har removed from g. 1.

B2 B2, the ends turned up to prevent it sliding endways;

C2 O2, the clasps..

b'L b2, the ends turned up as seen when clasped on .the web of the rail.

Operation.'

The fish-joint being constructed in the common and well-known manner, with bolts and nuts, as shown', the operation of my invention may be noted.

The bar is placed on the web ofthe rail, under the nuts, after they are turned on, which thickens the web under the nuts and prevents them from turning, as will be observed without further specication.

In this invention, I do not confine myself to forging the bar and` clasp together, with ends turned up, as shown; they may be thus forged, or made separate and connected by riveting, with ends lying on the web of the rail, or applied separate with ends of the clasps turned over on to the bar, instead of being welded or riveted to it. l

C lai/m.

What I claim as my invention, and desire to secure'
